“Visited the UTAR Campus, Kampar, Perak with my wife to enjoy some cycling in this lovely ‘green’ Campus which is built around rehabilitated ex-mining pools (now wetlands). Lots of herons, egrets, bitterns, etc.

“We arrived early and my wife, a great bird spotter, saw this unusual looking bittern. The sun was just coming over a ridge at 8.30 am, but views were good and this bittern definitely looked very pale. I am certain it is an adult male Yellow Bittern (Ixobrychus sinensis). However the bill was rather pink and the plumage pale pink. The outer flight feathers were black and the iris yellow as expected.

“Wonder if it is some mild leucistic form. We did see other ‘normal’ looking Yellow Bitterns.”
